CHECK
LIST FOR QUALITY CONTROL OF RCC WORKS
1.
Carry
out slump test at regular intervals to ensure proper workability.
2.
While
concreting cubes must be taken to as per IS: 456 – 2000 to ensure the quality
and strength of concrete by testing at 7, 21, and 28 days.
3.
Make
adequate number of cover blocks & chairs as per the required clear cover of
various members. Cover Blocks must be placed at minimum of 1m c/c
4.
Get
reinforcement physical test certificate from supplier/manufacturer.
5.
Ensure
that binding wires are adequately used for tying up of reinforcements.
6.
Check
spacing/length of hooks and overlaps. Laps shall be staggered.
7.
Check
vertical & horizontal alignment & strength of centering and shuttering.
8.
Ensure
that thickness/width of section is adequate for inserting vibrator; else inform
the design office for possible revision.
9.
Ensure
proper curing for required number of days. Use curing compound, if member is
not easily accessible.
10. Check that expansion/construction
joints are properly made & at correct location as per the drawings.
11. Make proper access/ walking
arrangement over slab for proper inspection & to avoid any damage to
reinforcements.
12. De-bonding compound to shuttering
materials.
13. Depth and width of all beams must be
checked.
14. Dimensions, diagonal, plumb and
supporting of lift pit should be checked properly.
15. All beam sides should be absolutely in
line and plumb.
16. Over all cleaning should be done
before concreting.
17. Walk-way Planks to be used while
casting the slab.
18. Slab concreting should be done in
strips (Bays) to avoid cold joints. Concrete should be placed within 30 minutes
for next strip otherwise keep the joint alive by putting one/two pans of
concrete at joint and vibrate it.
19. Spare Vibrator and needless must be
kept ready at the place of concreting.
20. Concrete should be poured from more
than 1 m height to avoid segregation
21. Reinforcement should be placed as per
specified spacing and diameter
These were the nice check lists of RCC quality control. It is true that proper uses of shuttering material in RCC work plays a vital roll in the quality as well. Thanks a lot for the sharing such a informative post.
